Several teens are under investigation after a disturbing video surfaced and circulated through a middle school in Powell, Ohio. The recording led authorities to believe the students mixed urine and semen into crepes prepared for their teachers, according to WBNS-10TV.

Olentangy Hyatts Middle School held a student cooking competition on Thursday as part of a “Global Gourmet” class, which was where the soiled dish was served.

Delaware County Sheriff’s Office spokeswoman Tracy Whited told the Columbus Dispatch on Monday that “one student filmed some of it, and the video made its way around the school and fortunately to school administrators.”

Unfortunately, the video emerged after teachers had eaten the student-prepared dish.

On Tuesday, Whited told The Washington Post that there were at least five victims. Eight students are being questioned, and some could face felony assault charges. “Others students may face misdemeanor charges, like complicity, but the investigation is still ongoing,” she said.

The Sheriff’s Office sent undisclosed evidence for forensic analysis. The lab results, Whited said, is “the only way we’ll really know.”

The local school district issued a statement to 10TV, saying: “Leadership and local law enforcement are conducting a thorough investigation into this incident, and anyone found in violation of school policies will be held accountable for their actions.”

The district added, “We are also focusing our efforts to support the teachers impacted by this incident,” though teachers have been instructed not to discuss it.

In an interview with 10TV, one student’s attorney cautioned the public against jumping to conclusions. This “easily could have been a prank,” he said.
